YOU WILL BE WORKING AROUND THE ENGINE AND EXHAUST SYSTEM
DURING INSTALLATION. ENSURE THAT THE ENGINE AND EXHAUST
SYSTEM HAVE FULLY COOLED TO PREVENT INJURY.
A FACTORY SERVICE MANUAL WILL BE HELPFUL IN PERFORMING THIS
INSTALLATION. DO NOT ATTEMPT TO PERFORM THIS INSTALLATION IF
YOU ARE NOT CONFIDENT IN YOUR ABILITY TO COMPLETE ALL OF THE
STEPS IN THE PROCEDURE; CONSULT A TRAINED TECHNICIAN.
IMPROPER INSTALLATION COULD RESULT IN SERIOUS INJURY OR
Installation of this kit REQUIRES carb re-jetting over and above what may have
already been performed for pipe installation. This is a complex procedure and we
strongly recommend that this be performed by your dealer or a competent
mechanic. If you choose to attempt this on your own, you will need the service
manual for this model as carb removal and disassembly instructions are not
provided in this literature. THE FOLLOWING JETTING RECOMMENDATIONS ARE
INTENDED AS A STARTING POINT. Optimal performance and driveability may
require fine tuning. Adjustments may be needed for higher altitudes. General rule
of thumb is one jet size smaller for every 3000-4000 feet of elevation.
Rejetting and tuning a motorcycle can be a complex task. Due to factors outside of
our control, Küryakyn will not be held liable for any labor costs incurred from
installation of this kit.

The installation of any high performance exhaust system can cause a
“lean” fuel/air mixture. A “lean” fuel/air mixture can cause engine
overheating resulting in severe engine damage. Küryakyn
recommends rejetting carbureted bikes.
Remove the stock air cleaner and components to the point shown in
PIC.1. The stock plastic airbox adapter “A” and stock mounting brackets
“B” will remain in place.
Insert both flanges of the rubber adapter through the mounting bracket
as shown in PIC.2. The hardware components used for installation are
placed near their respective mounting points:
•”A” Socket head cap screw - 30mm long, tapered bolt cap, and
two spacers. The spacers are placed between the chrome, and
the stock mounting brackets.
•”B” Socket head cap screw - 15mm long , tapered bolt cap
•”C” Socket head cap screw - 30mm long, tapered bolt cap, two spacers (place between
chrome and stock brackets), and flange nut.
•”D” Mounting holes.

The opening in the adapter boot must be slipped over the flange of the stock airbox and secured
with the stock clamp. Install the mounting bracket as shown in PIC.3. Secure this
assembly to the bike with the hardware specified in the previous step.
See PIC.4. Plug the extension into the float bowl vent hose and add the short
section of hose included. This will plug into the 90 degree fitting on the back side
of the Hypercharger.
See PIC.5. This step can be performed without disassembling the air cleaner. The
front half was removed here for a better picture. Only the round “trap door” need
be removed. “Work” the radiused flange of the adapter into the inlet hole of the air
See PIC.6. Fold the radiused flange back to expose the three mounting holes.
Secure the air cleaner to the bracket using the three 1/4–20x1/2” Socket head cap
screws and Nylock nuts.
Replace the trap door on the Hypercharger. Connect the newly extended float
bowl vent hose to the 90° fitting installed on the back of the air cleaner. On the
left side of the engine, next to the front cylinder you’ll see the two chrome lines
that go to the fresh air pump. The small rubber hose clamped to these lines is a
vacuum hose. Find the splice in this vacuum hose. Remove the splice, and in its
place insert the enclosed “T” fitting. Run the enclosed length of vacuum hose from
this “T” fitting to the vacuum nipple on the bottom of the Hypercharger.
Double check the tightness of all related fasteners, check for hose
clearance and check throttle for correct operation, making sure it returns
properly, before starting bike.
ROTATE THROTTLE AND CHECK THAT IT MOVES FREELY AND
RETURNS TO CLOSED BEFORE STARTING BIKE. FAILURE OF
THE THROTTLE TO RETURN COULD RESULT IN LOSS OF
CONTROL CAUSING SERIOUS INJURY OR DEATH.
It is the installer’s responsibility to ensure that all of the fasteners
(including pre-assembled) are tightened before operation of the
motorcycle. Küryakyn will not provide warranty coverage on products
or components lost
due to improper
installation or lack of
and maintenance are
required on all
